AMMUNITION FOR LINE-THROWING GUNS AND THE LINE-CARRYING RING THEREFOR.

Application filed October 16, .1923. Serial No. 668,875.

(FILED UNDER THE AG'LOF MARCH 3, 1883, 22 STAT. L, 625.)

T all whom it may concern.

Be it known that I, JOHN W. S'rooKnT'r, a citizen of the United States, and a resident of WVashington, District of Columbia, have invented an Improvement in Ammunition for Line-Throwing Guns and the Line-Carrying Ring Therefor, of which the following is a specification.

The inventiondescribed herein may be used by the Government, or any of its officers or employees in prosecution of work: for the Government, or by any other person in the United States, without payment to me of any royalty thereon, in accordance with the act of March 3, 1883.

This invention relates to the ammunition for line throwing guns and the line carrying ring therefor. p

In line throwing guns it. is desirable that the propellent charge and its container be entirely expelled from the gun when fired or entirely consumed by the gases from the propelling charge, so that no unconsumed particles will be left when the next charge is inserted.

The main object of the invention is, therefore, to provide a round of fixed ammunition having a propellent charge and container fixedly connected therewith in such a manner that the projectile and its propelling charge may be loaded into the gun at its muzzle end as a single unit, and such that after discharge of the gun, no portion of the powder container will be left in the bore of the gun, to interfere with the loading of the next round into the gun.

A further object of the invention is to provide a projectile formed in rear of its center of gravity with means against which a line carrying member is adapted to seat as the projectile passes from the muzzle of the gun.

\Vith these and other objects in View, my invention resides in the novel arrangement and combinationof parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

Practical embodiments of the invention are shown in the accompanying drawing, wherein Fig. 1 is a fragmentary View in side elevation, partly in section,,of. a round constructed in accordance with the invention;

Fig. 2 is a similar view of a modified form of the device; and

Fig. 3 is a view in elevation of the lin. carrying ring; and. r

Fig. 4 is a section through the ring. I

Referring to the drawings by numerals of reference y A round constructed in accordance with my invention consists of a projectile 1 formed preferably with an annular shoulder 2 located rearwardly of the center of gravity of the projectile and with a reduced base portion 3., v

Secured t0 the base portion 3, in any suitable manner, as by frictional contact there-- with, is a container 4 in which is carried the propelling charge. This container 4 may be of any desired type. In one embodimentof my invention the container is provided with a series of perforations 5 through which the gases formed by the ignition of the propellent charge may escape.

The propellent charge, not shown, is packed within the container. To prevent particles or grains of the propellent charge from escaping through the perforations 5 the container may be encircled by a gauze fabric 6. The fabric is preferably held in place by shellac or other suitable waterproof adhesive, in order to keep moisture from the powder charge, which would otherwise be ruined if allowed to get wet.

When the igniting primer is fired the flash passes through the perforations igniting the propellent charge. The gases of the propellent charge, escaping through the perforations, serve not only to propel the pr0- jectile from the gun barrel but also the container at, which is thus expelled from the I In the modification shown in Fig. 2 the projectile is the same as that heretofore described but the container in this instance is formed with walls 4 of inflammable material, such as nitrocellulose, which is ignited by the flash of the primer igniting the propellant charge and is entirely consumed therewith.

As the projectile passes from the gun the shoulder 2 is brought into contact with aline carrying ring 7 shown in Figs. 3 and 4, which is suitably mounted upon the gun, adjacent the muzzle thereof, preferably, in a counterbore in the muzzle as described in my copending application Serial No. 668,874: filed Oct. 16, 1923, now Patent No. 1,483,129, issued Feb. 12, 1924, and is provided with two openings or eyes 8, for the attachment of the projectile line. As stated heretofore the shoulder 2 is preferably located rearwardly of the center of gravity of the projectile. This arrangement is preferred in order that the projectile as it carries the ring on its trajectory may beproperly balanced so that tumbling of the projectile will be prevented and the breaking of lines, a common occurrence with projectiles heretofore used may be avoided.

The line ring'7, may, if desired, be provided with a reduced portion 9, for supporting it in a suitable counterbore in the barrel of the gun at the muzzle end. In order to provide ample strength and to prevent splitting the ring 7 when the engaging shoulder 2, on the projectile comes into engagement with the ring where a ring seated in the counterbore is employed, I provide that portion 10 of the line carrying ring, which is exterior or forward of the counterbore in the gun with a greater cross-sectional area than the remainder of the ring.

I claim:

1. A round of fixed ammunition, including a projectile formed with an annular shoulder toward its base, a perforated container secured to the base and a gauze fabric covering the container.

2. A round of fixed ammunition, including a projectile formed with an annular shoulder toward its base and a perforated container connected to the projectile in such manner as to be expelled therewith from a gun on firing the same, said container being adapted to fit over the base ofthe projectile in the rear of the shoulder.

3. A round. of muzzle loading fixed ammunition, including a projectile formed with an annular enlargement near its base,

and a water proof inflammable propellent container fitted over the rear end of the projectile and resting against the enlargement.

4. A round of muzzle loading fixed am munition, including a projectile formed with an annular enlargement near its base which servesas a line rin'gcarrying member and a water proof combustible propellent container connected to the base of the projectile and resting against said enlargement JOHN W. STOCKETT.
